BURT THELEPHORACEAE OF NORTH AMERICA. X

ruhiginosa was stated by Fries, Elenchus Fung. 1 : 174, in the 

 comment of the original description of Thelephora leprosa 

 collected in Brazil. If the specimen of Thelephora leprosa 

 upon which Leveille based his transfer of this species of 

 Bymenochaete is still in the Museum of Paris Herbarium and 

 is from the original collection, comparison with this specimen 

 may show that H. reflexa should be regarded as a synonym 

 of T. leprosa. The structure in section of H. reflexa is very 

 like that of H. unicolor, but the hymenium is of different color 

 and all the collections of H. unicolor have the margin closely 

 adnate.
